Cheap Hyundai Ioniq Lambda Sensor

It depends on the variant. The petrol-hybrid (1.6 GDi hybrid) and plug-in hybrid Ioniqs do have lambda sensors as part of their exhaust and emissions management systems, because they run a petrol combustion engine. The pure electric Ioniq (Ioniq Electric) has no combustion engine whatsoever, so it has no exhaust system and no lambda sensor — if you drive an electric Ioniq, a lambda sensor is not a part that exists on your car.

The Hyundai Ioniq (Mk1) ran from 2016 through to 2022, with a facelift in 2019, and the 1.6 GDi hybrid engine carried across the full production run, so the engine code and fundamental exhaust layout remained consistent. However, the 2019 facelift did bring updates including emissions calibration changes, and whether a pre-facelift lambda sensor crosses that 2019 boundary without issue is something you should confirm with the breaker against your exact registration and engine code rather than assume. Engine code matching is the key check here.

Trim level — whether SE, SE Connect, Premium, or Premium SE — does not affect lambda sensor fitment on the Ioniq hybrid; the sensor is determined by the engine and emissions specification, not by interior or equipment grade. You may find minor cosmetic differences in how ancillary components are routed or clipped on higher-spec cars, but the sensor itself should be the same across trims sharing the same engine code. Always cross-check the engine code on your V5C with the breaker to be sure.

Both the Ioniq Hybrid and Ioniq Plug-in Hybrid share the 1.6 GDi petrol engine, so the lambda sensor application is closely related, but the two variants can have differences in their exhaust and emissions calibration setup. This is firmly confirm-with-the-breaker territory — supply your registration and engine code and ask the dismantler to verify the part number matches your specific hybrid type before purchasing.

Lambda sensors from across the Ioniq's 2016–2022 production run were built to Euro 6 standards, so you are not crossing a major emissions-era boundary within this model's lifespan in the way you might with an older vehicle. That said, a faulty or incorrect lambda sensor can cause the engine management system to run incorrectly, potentially leading to an emissions failure at MOT, so correct fitment by engine code is important. Confirm with the breaker that the sensor matches your engine code and model year before buying a used example.

The most reliable approach is to give the breaker your full registration number and, if possible, your engine code from the V5C or under the bonnet — for the Ioniq hybrid variants this will be the 1.6 GDi unit, but the breaker can match the exact part. Position also matters, as some engines use both a pre-cat (upstream) and a post-cat (downstream) sensor, so tell the breaker which one you need — NS or OS if applicable, and upstream or downstream. Never assume a sensor fits based on year alone; always confirm with the breaker.
